1136500171 Cooling water pump for 6BG1/6BD1 engines in EX200-5 excavators
Part number 1136500171 is a cooling water pump used in Isuzu 6BG1/4BG1/6BD1 series diesel engines. It is commonly found in the engine cooling systems of excavators and construction equipment such as the EX125WD-5, EX200-5, EX210H-5, and SH200/SH280 models. This water pump is responsible for circulating the engine coolant, using an impeller to propel the coolant flow, effectively dissipating the heat generated during engine operation and maintaining the engine within its ideal operating temperature range. This protects the cylinder block, pistons, and other components from overheating damage. The product features a robust structure and is made of high-temperature resistant metal materials, ensuring stable operation in heavy-duty, long-term working environments.
